The mass of one electron is 9.11 X 10(-28) grams. A uranium atom contains 92 electrons. Find the total mass of the electrons in a uranium atom.
Express your answer in scientific notation.
----------
Use * for multiply, not x
---------
Mass of 92 electrons = 9.11E-28*92
= 838.12E-28
= 8.3812E-26 gms or
gms
The input data had 3 significant figures
--> gms
----------
"E format" is commonly used for scientific notation.
It's easier to type and to say.
--> 8.38E-26 gms
